Custom Extension Screw Collar

Adds 1.5 inches of stroke to a 6, 12 or 20 ton bottle jack by extending the screw without increasing the starting height when used with a jack pad or jack extension. Please use the above form to fill into the information based on your jack.

Watch the video below to help you step by step how to measure your jack and then provide us with that information.  We will create a custom extension screw just for you and your jack so you are able to use our products.

Extension screw collars provide the proper fit for jack extensions and jack pads but they also give the operator 100% of the usable stroke of the jack. The collars are easy to install taking only a few seconds and they can be removed just as easily.
